Align components using calipers, rulers etc. and clamp pieces
Weld components using manual or semi-automatic welding equipment in various positions (vertical, horizontal or overhead)
Repair machinery and other components by welding pieces and filling gaps
Test and inspect welded surfaces and structure to discover flaws
