Sheet metal welding: MIG vs TIG

For large-scale metal fabricators like us at ZhongXin Group, sheet metal welding is a major part of the fabrication process.

Sheet metal components that include two or more components of sheet metal, or profiles and shapes that cannot be cut or formed from a single sheet of material and thereby are impossible to be manufactured as one, may well rely on welding to combine all individual sheet metal components into the final fabricated product.

Highly skilled welders with high levels of knowledge and inspection experience are needed to produce high quality, robust, clean and aesthetic welds, particularly with stainless steels and aluminium, that consistently meet the customer specifications.

For complex fabrications that demand high precision, greater control and tight dimensional tolerances the main aim is to avoid distortion and burn-through while ensuring necessary mechanical strength for the application. To do this, metal fabricators need to select the correct welding techniques, employ the latest technology and use skilled and qualified staff .

Two of the most common sheet metal welding techniques include MIG (Metal Inert Gas) welding & TIG (Tungsten Inert Gas) welding. This article will explore the main differences between the methods and for what applications metal fabricators are most likely to employ the two methods.

As leading sheet metal fabricators, ZhongXin offers extensive MIG and TIG welding services. We currently house 20 welding bay facilities (six dedicated to stainless steel) and operate two fully automated, ABB robot MIG and TIG welding cells, accompanied by stud and spot-welding machinery that enables ZhongXin to fulfil almost any customer requirement.

Recognised as a core skill for our business, our award-winning st has a strong focus on high-level welding, and our welders work 24/7 to deliver coded welding to desired standards and in-house dye penetration.

Selecting the most efficient welding solution should be carried out on a case-by-case basis, and therefore our expert New Product Introduction Engineers will take time to determine the best materials and welding processes required for your specific design and product application.
