What is

Custom Stainless Steel Fabrication

Custom stainless steel fabrication is among the services offered by Topweld General Engineering and it covers many different applications for stainless steel welding. We work on projects of varying complexities in industries ranging from general construction to automotive. However, the term is rather vague by itself, and there is often confusion as to what kind of work custom stainless steel fabricators such as ourselves can do. We wish to make that clear with this short blog post. With this information, we hope to spread correct information regarding the services we offer, and hopefully reach out to those who would otherwise need our help.

What is stainless steel fabrication?

Metal fabrication – and to an extent, stainless steel fabrication – is the process of turning raw materials, often plate metal and tube metals, into finished products through the process of cutting, forming, assembling, and welding. This is different from forging and machining, in that it focuses more on the assembly process of manufacturing by means of welding. As such, most fabricators are trained welders, but not all welders are trained at fabrication. Both manual labor and automation are used in fabrication, and even with the benefits of having machines do the more difficult and repetitive tasks, it still takes a well-trained fabricator to produce good results. Stainless steel is among the most common metals to work with for a multitude of reasons.

Applications of
Custom Fabrications

Custom fabricated stainless steel is everywhere from homes to factories. Much of it could be attributed to the fact that it is one of the most common ways we process the alloy. Listed below are some of the fabrication and welding services in New South Wales that Topweld provides. 

General Construction

Structures such as handrails, awnings, fences, and gates are made with steel or welding services in New South Wales for strength and durability. These are some of the easier projects to work on because their designs are fairly straightforward and they do not follow strict safety guidelines as some of the other entries in this list, but that does not mean we put any less effort into them compared to other projects.

Storage
Vessels

Storage vessels such as water tanks and storage silos are used in high-density housing and the agriculture industry. They are usually made of stainless steel to prevent corrosion, which could ruin the contents of the vessels. Similar to them are pressure vessels, which are designed to store their contents under a very specific amount of pressure. Because of the risks involved in structural failure, especially if they contain volatile material, they have to follow strict design and construction guidelines. The metal fabrication in New South Wales that we operate in Topweld workshops abides by these guidelines to the letter, so you can lay your worries to rest on that front.

For Services like

Pipes and Tubes

Pipes are commonly used to transport liquids and granular materials around the factory as they are being processed into finished goods. Tubes, on the other hand, come in a variety of shapes and are mostly used for structural purposes. Both have their own use case and require welding to be installed in the places they need to be. Topweld’s pipe and tube welding services include cutting and installation for machines and buildings.

Stainless Steel Sheet Metal

Sheet metal fabrications are used for roofing, plating, and automotive bodies. They are incredibly versatile but require a careful and coordinated eye to weld to avoid burning through them accidentally due to their thinness. Handing the material, therefore, is not as easy as it looks. Lucky for you, our stainless steel fabricators are all too familiar with this problem and have honed their skills to do their work with both speed and precision.

Questions And Answers

Stainless steel fabrication is the complete process of cutting, forming, assembling, and welding metals like stainless steel into a finished product.

Welding is simply the joining of two or more pieces of metal using heat whereas metal fabrication also includes cutting and bending the metals into individual parts.

There are four major steps in stainless steel fabrication: cutting the metal, bending it to a desirable form, assembling, and combining the pieces together by means of welding.

Sanitary Welding

nAs one of the premier choices for welding services anywhere in Canberra and New South Wales, Topweld General Engineering has worked with many industries in the past, among them are those that deal with the production and processing of food, medicine, and other types of products that humans or animals consume. Because of the health concerns associated with the mishandling of these products, sanitary welds need to follow strict guidelines. Sanitary welding is a particular process of joining two pieces of metal together in order to create a seal that is impermeable to fluids and gas. The sanitary welding process is often used in the food and beverage industry, as well as in the pharmaceutical industry, in order to create a sanitary environment that is free of impurities. It is not a job that just any welder can do, but fortunately, the expert craftsmen in Topweld aren’t just any welders.n

What Makes a Weld Sanitary?

nAs previously mentioned, not all welds can be considered sanitary, because there are specific criteria that the weld must meet in order to achieve that classification. There are a few key factors that contribute to what exactly is sanitary welding. Without going too much into technical jargon, the following are:n

    n

  1. The weld itself must be free of any imperfections or defects that could provide a foothold for bacteria or other contamination. 
  2. n

  3. The weld joint must have a smooth surface, free of any sharp edges or burrs that could harbor bacteria. 
  4. n

  5. The weld joint must be properly cleaned and disinfected to ensure that it is free of any harmful microorganisms.
  6. n

nOf course, there is much more to the craft than these basic guidelines. It takes years of experience as a welder in order to ensure that they are met. For that reason, we reserve sanitary welding jobs for the most talented metal fabricators in the company with sufficient training and expertise under their belt.nn

Materials Used

nThere are a variety of metals that we use for sanitary welds. Some of the most common include stainless steel and aluminum. They may look very similar, but each of these metals has its own benefits and drawbacks that should be considered when choosing which one to use. During the design phase, the welder picks the most appropriate alloy to use given a specific application.nnStainless steel is easily the most popular choice for sanitary applications owing to its high durability and resistance to corrosion, which makes it ideal for use in wet environments such as the interior or pipes. Additionally, it is easy to clean and sterilize, further adding to its appeal. When welding stainless steel, we pay close attention to the filler metal so as to maximize the effect of the chromium anti-rust barrier. Its main drawbacks are that the alloy has very poor electric conductivity and it is much more expensive than the alternative. Aluminum, on the other hand, is also a metal our team specializes in that is quite popular in sanitary welds. It is one of the easiest metals to fabricate because it is malleable, lightweight, non-toxic, and resistant to corrosion. It performs worse, however, in aqueous environments, so the alloy is limited in its capabilities compared to stainless steel. That said, aluminum welding is still widely used in other industries that don’t use saline water. With all that said, which one of these two alloys do you think would best suit your project?n

TIG Welding VS. MIG Welding Technique

nTIG welding (Tungsten Inert Gas Welding) is the preferred technique in sanitary welding as it provides the welder with increased control over their work. In the hands of a trained metal fabricator, sanitary TIG welding can produce clean and strong welds that are less likely to harbor other impurities. When calibrated properly, MIG welding (Metal inert gas) can also be used for sanitary work, especially when working on large metal fabrications. The main issue is that the speed and streamlined experience of this welding technique may become its downfall when it comes to precise joints and sections of a sanitary weld.n

What Are the Uses of Sanitary Weld?

nSanitary welds creates aseptic conditions in metallic surfaces that protects materials passing through them from becoming contaminated by unintended reactants, and other harmful substances. They also allow for easy and reliable cleaning.n

Food Manufacturing

nThe most common use of sanitary welding is in complex machinery and food grade equipment that handles the processing of raw materials into food that will be sold to and consumed by a large number of people. For this reason, the industry must abide by strict rules in all stages of production in order to ensure public health safety. Sanitary stainless welding is a good example of the application of this type of work in the food industry.n

Medical and Pharmaceutical

nSimilar to the food industry, the medical and pharmaceutical industry must also follow guidelines such as sanitary weld that are meant to ensure that their products are safe to consume or be used in the medical environment. Syringes, for instance, must be completely free of contaminants before they can be used as they will come into direct contact with a person’s bloodstream.n

Agriculture

nFarmers usually process their crops in bulk, so it is very important to keep the machinery and other food grade equipment they use clean and safe to avoid harmful substances from contaminating and potentially ruining an entire yield. The rice mill or the many milk processing equipment used in dairy industries make for good examples. Like processed food, sanitary stainless steel welding plays a vital role in maintaining the quality of these machines and their products.n

Petrochemicals

nSanitary welding is also important in handling petrochemicals that produce products like detergent, paint, and even explosives. For these products, it is incredibly important that the interior is clean with a smooth surface so that no material that is unaccounted for ever gets mixed in during the manufacturing process. Once again, stainless steel is a fantastic material to utilize for this purpose.n

Plumbing

nKeeping the water supply and drainage systems in a residential building prevents blockages, leaks, and of course, water contamination. Not to be confused with plumbers, sanitary pipe welding is concerned with the structural integrity of the entire pipe system, rather than isolated problems.n
