What Welding Services Do We Offer?

Welding joins metal parts by melting the base material and/or filler material to form a strong joint. At Golift, we offer MIG welding, TIG welding, spot welding, and robotic welding for carbon steel, stainless steel, aluminum, and other metals. We handle both small precision assemblies and large structural weldments.

MIG / GMAW

Gas Metal Arc Welding — fast production welding and structural joints for steel, stainless and aluminum.

TIG / GTAW

Gas Tungsten Arc Welding — precision, cosmetic welds and thin materials such as stainless, aluminum and copper.

Spot / Resistance

Resistance spot welding — fast joining of sheet metal without filler material.

Robotic Welding

Automated MIG/TIG — high-volume repeatability and consistent weld quality.

Welding Equipment & Capacity

Step 01

Welder Training & Procedure Control

Welders are trained and qualified, and welding procedures are controlled for each material and joint type.

Step 01

Step 02

Joint Fit-Up Inspection

Joint fit-up is inspected before welding — alignment, gap, and tack quality confirmed against the drawing.

Step 02

Step 03

In-Process Weld Bead Inspection

Weld beads are inspected during welding — bead profile, continuity, and fusion checked as the joint is made.

Step 03

Step 04

Visual Inspection

Finished welds are visually inspected for porosity, cracks, spatter, and overall alignment.

Step 04

Step 05

Dimensional Check After Welding

Assemblies are measured after welding and cooling, confirming final dimensions against the drawing.

Step 05

Step 06

Leak & Load Testing (Optional)

Leak or load testing is performed on request for tanks, pressure parts, and structural weldments.
