Welding Services 

Of all the sheet metal forming and fabricating services, welding remains the area where the skill and experience of our staff is expressed in each and every part.  Classic Sheet Metal maintains a welding department of structural and sheet metal welding services by certified welding professionals, many with 15 to 20 years of experience in stainless steel, copper, aluminum, and many other ferrous and non-ferrous materials.

Our Spot and TIG/MIG welding expertise assures better penetration, better finishing and finer looking weldments.

The fabrication of a sheet metal chassis often requires some method of assembly. This assembly can be achieved by welding and spot welding component sheet metal parts or or adding various types of hardware such as weld nuts or hinges.  This is an accurate, economical, and efficient method of assembly.

Precision Welding Services Defined

Welding is a fabrication or sculptural process that joins materials, usually metals by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material (the weld pool) that cools to become a strong joint, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. 

Classic Sheet Metal uses two methods of welding for production runs.
     
Spot Welding uses tungsten rod or coiled wire to squeeze two metal parts together while introducing a high wattage/low voltage current causing the material to flow and thereby fusing the parts together.
    
Welding (TIG/MIG welding) uses a tungsten rod to arc a strong, higher voltage (AC for aluminum) to the parts, melting them together resulting in a very strong filleted weld. Sophisticated electronic devices now control both of these methods of welding.

This is in contrast with soldering and brazing, which involve melting a lower-melting-point material between the workpieces to form a bond between them, without melting the workpieces.
