Welding can be used to solve certain problems such as creating complex parts (welding pieces together to make one part), creating watertight joints, or adding strength to an enclosure.
At Protocase, we use Cold Metal Transfer (CMT) welding. While it appears similar to wire-feed MIG welding, there are differences.
In MIG welding, filler metal transfers via sputtering at very high temperatures.
In CMT, the wire is heated enough to melt the tip, and transfer occurs by physical contact. This method generates just one-tenth of the heat of MIG welding, which prevents warping or melting back, even for thin sheet metal.
We can weld Cold Rolled Steel, Galvanneal, Stainless Steel, Aluminum and Copper*.
*Copper is usually brazed.
Both spot welding and seam welding are standard processes that are a part of our fast 2-3 day manufacturing lead time.
No, not all designs require welding. Many enclosure types, such as our standard U-shape (clamshell), do not.
In this case, one section of the enclosure contains small flanges with self-clinching nuts. The other section uses mechanical fasteners such as machined or sheet metal screws.
Our experts can design your custom enclosures exactly as you want them.
