Hello!
We students here at NIT Calicut,India are competing for a vehicle design & fabrication contest- Baja SAE Asia 2010. We have chosen 4130 Chromoly Alloy Steel tubings/pipes as the material for our Roll Cage(Chassis). The following are the specs:
Tubing Material: 4130 Chromoly Alloy Steel
Outer Dia(OD)= 1.25 inch
Wall Thickness= 0.065 inch (1.65 mm)
The roll cage has to survive the harshest of punishment of a 4 hour endurance race on an off-road track. I would really appreciate if answer the following queries:
1. Does TIG Welding have a clear advantage over MIG and Arc Welding in our case? If so, what are the advantages?
2. Does TIG Welding require stress relieving/ heat treatment?
Thanking you in anticipation
Kind Regards
