TIG vs MIG welding: choosing the right process for your part

TIG welding

TIG uses a tungsten electrode and a separately fed filler rod. It is slower but gives precise, neat welds with little spatter. It's the usual choice for stainless steel, aluminium, thin sheet and visible welds that need to look good.

MIG welding

MIG feeds a wire continuously through the torch, making it faster and more economical on longer welds. It suits mild steel frames, thicker material and structural joints where appearance matters less.

Which to choose

• Visible, cosmetic welds on stainless or aluminium: TIG.
• Thin sheet where distortion must be minimised: TIG.
• Long structural welds on mild steel: MIG.
• Cost-sensitive production frames: usually MIG.

How we work

We offer both in-house. If your drawing doesn't specify a process, we'll pick the one that meets the requirement at the lowest cost and can grind, grain or polish welds to match the finish you need.
