Welding Sanitary Stainless Steel Tubes and Fittings

This article will talk about the most commonly used types of welding for sanitary valves, tubes and fittings in Malaysia.

The most popular welding method in the food world is arc welding, which consists of MIG (metal inert gas) and TIG (tungsten inert gas). MIG, where the welding rod is often automatically fed is sometimes used, but mostly only on structural parts, skid frames for example. TIG is a form of arc welding where the filler metal is manually hand fed by the welder.

MIG vs TIG Welding

TIG is by far the most common type of welding we see in the food and beverage industry, especially for thinner materials. Because its a manual process, it requires a higher amount of skill, and has slower welding speeds compared to MIG.

TIG can be automated by using an orbital welding machine. It is a process where the arc is rotated mechanically around the joint. Because it is done almost entirely by machine, the welds are consistent and high quality. The only drawback is the high investment cost of buying the machine. Orbital welding is usually seen in the pharmaceutical industry.

Only a little welder input is required for smooth welds when done by machine.

While we do supply Food Grade Stainless Steel Valves, Tubes, and Fittings, we do not have the manpower or expertise for the actual welding. But if you have trouble looking for such welders, we can recommend some of our capable customers for any of your projects.
