Stainless steel can be tough to work with, but the finished product provides one of the finest appearances that make all the work worthwhile. It is widely understood that a finer grit in a sanding sequence removes the previous scratch pattern and improves the finish, but there is a lot to be aware of regarding the overall steps required when using the many grit sequences to achieve the desired ...

Grinding the die face or blank holder with respect to compressive thickening will help to reduce the resistance in the drawn-shell corners and allow greater blank holder force to be applied to the blank that will form the drawn shell side walls. Too often the thinking is if the part is flat, a perfectly flat blank holder can be used.

Welding Heat Sink- Applying a heat sink behind the weld or on the surrounding metal of a weld will help keep the the heat from spreading and allows you to weld without damaging the metal surrounding the weld as much. Our copper weld backers help to keep a welds from blowing through the metal and also act as a heat sink.

SPOT WELDING can cause fire or explosion. Sparks can fly off from the welding arc. The flying sparks, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of elec-trode to metal objects can cause sparks, explosion, overheating, or fire. Check and be sure the area is safe before doing any welding.

The last step is to grind down the weld with a 3M reinforced weld-grinding wheel. Grind it almost flush, maybe leaving a very slight crown. You must avoid touching the panels with the grinder as they can get too thin really fast using this tool. It's better to leave just a little extra rather than go to far.

Share. Tweet. #7. 10-28-2006, 03:38 PM. I'm assuming if you have the nut, there's a hole in the plate that it centers on. Run a bolt through it and tighten it down lightly. That will a) help keep the nut from twisting up on one side, and b) act as a heat sink for the small threads on the inside of the nut.

GRINDING. Corrosion resistance is dependent on the fineness of the surface. MECHANICAL POLISHING. Almost as effective to electrolytic polishing depending on the grit used: the finer the surface, the better the corrosion resistance. BRUSHING.

When welding pipe with TIG, use pure argon and gas hoses of good quality. Spread out the gas on the root side. Gas flow (2)-20 I/min. Purge the pipe with 7-10 x the enclosed volume. Keep the shielding gas on until the weld has cooled to below about 200°C. Using a gas lens is recommended–it provides a better gas shield.
