Common Questions

Welding FAQs

What's the difference between MIG and TIG welding?
MIG (Metal Inert Gas) is faster and better for production work. The electrode is continuously fed, making it ideal for thicker materials and structural applications. TIG (Tungsten Inert Gas) gives more control and is better for precision, thin-wall, and aesthetically critical work. TIG uses a non-consumable electrode and separate filler, allowing precise control of heat and puddle. For most structural steel, MIG is faster and cost-effective. For stainless steel and aluminum, TIG typically produces superior quality.
Can you weld aluminum?
Yes. We weld aluminum alloys including 6061, 5052, and others. TIG is required for aluminum welding to maintain quality and prevent porosity. MIG is not suitable for aluminum in our process. Aluminum requires careful technique due to its lower melting point and oxide layer. We have specialized equipment and certified welders experienced in aluminum joining.
What tolerances can welding hold?
Welding is not a precision process in terms of dimensional accuracy. Typical weld bead width is ±0.5–1.0mm. If you need tight dimensional control, base geometry should be cut and formed to spec, then assembled and welded. Our laser cutting and CNC forming provide tight tolerances; welding joins the pieces. For precision assemblies, we minimize heat distortion and can add locating pins or fixtures to hold geometry.
What is full-penetration welding?
Full-penetration welding means the weld metal flows completely through the joint, creating a continuous connection from front to back. This is required for structural applications where maximum strength is needed. It requires proper joint design, filler material selection, and skilled welding technique. All structural work at PT Metals is full-penetration unless otherwise specified.
How do I submit a welding project?
