Not too swift on some technical stuff. I thought maybe some of you educated folks could help me.
H&S 4500 UNI-SPOTTER STUD WELD GUN -VS- Chicago Electric (Harbour freight stuff)
Ok Stud welds are about one second welds--so given that if I have say 1/16" sheet metal with polyurethane insulation sheet directly behind the placement of the studs (can not remove before welding) will this stuff melt under the heat much? How much heat can be expected to be generated? Fire issues? The insulation would not be visible so scorch marks--cosmetic is not an issue. Any melting I guess could be ceased by water cooling imediately after the fastening? what kind of compromising of the weld strength would occur under this action?
How would a stud weld hold up as the actual faster for the two sheetmetal panels? Anyone know how they would compare to say 1/8" pop rivets? sheer stength---etc
Thanks for any comments
