Welding

We offer a complete range of metal welding capabilities including MIG, TIG, ARC, Brazing, Silver Solder and Spot Welding. We can weld aluminum, steel or stainless steel. Precision fixtures can be made so your high tolerances can be maintained. LM Designs has been welding for over 35 years, therefore we are familiar with the heat effects on material.
We have plasma cutting capabilities of up to 1/2" thick steel, stainless, brass, copper, and up to 3/4" thick aluminum plate.
LM Designs welds most Thermoplastics. Using quality welding rod we are able to weld a variety of plastics including HDPE, LDPE, PVC, PP, ABS, etc...

 

MIG Welding

Gas Metal Arc Welding (GMAW) is frequently referred to as MIG welding. MIG welding is a commonly used high deposition rate welding process. Wire is continuously fed from a spool. MIG welding is therefore referred to as a semiautomatic welding process.

Benefits

  • All position capability
  • Higher deposition rates than TIG
  • Long welds can be made without starts and stops
  • Minimal post weld cleaning is required

TIG Welding

Gas Tungsten Arc Welding (GTAW) is frequently referred to as TIG welding. TIG welding is used when high quality, precision welding is required. In TIG welding, an arc is formed between a non-consumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and molten weld pool. If filler rod is used, it is added to the weld pool separately.

Benefits

  • Superior quality welds
  • Welds can be made with or without filler metal "
  • Precise control of welding variables (heat)
  • Free of spatter
  • Low distortion

At LM Designs our in house welder has 35 years of experience in all aspects of welding including plastic.

  • TIG (aluminum, stainless steel, steel)
  • MIG (aluminum, stainless steel, steel)
  • ARC (stainless steel, steel, cast iron)
  • Flame Brazing (cast iron, brass, bronze)
  • Silver Solder (brass, bronze, copper)
  • Lead Solder (sheet metal, copper, brass)
  • Plasma Cutting (most materials up to 3/8" thick clean cut and up to 1/2" thick rough cut.
  • Plastic (PVC, ABS, poly, natural poly, Teflon, polypro...)

As any good welder will tell you, the secret to a sound weld with a pleasing appearance is setup and technique. The picture (right) is a 4130 chrome-moly pipe joint on a custom sand rail frame we built. As you can see the nicely machined pipes will product a solid joint with TIG welding using ER80S-D2 filler and the proper welding technique.

For this project welding technique consisted of tight joints, sufficient tacking to prevent twisting and warping, preheating before welding, and slow cool down with insulated blankets post welding. Not to mention proper machine settings, correct filler material, and the list goes on.

This attention to detail is what 35 years of experience will bring to your welding project.
