Have both would like a mig but maws says old dad spending to much money on 59 Apache. Would get rid of her but the title to the Harley is in her name also. Sure would miss the bike! | | | | | Joined: Jan 1970 Posts: 365 Shop Shark | | Shop Shark Joined: Jan 1970 Posts: 365 | I would say the stick (SMAW) is at least twice as strong as a brass weld. I can find out the tensile strengths of each, but it will take a little time. The 7018 rod is 70,000 psi tensile strength, while the 6011 is 60,000 psi--the first two numbers in the rod ID is the tensile strength. I am not sure about brass tensile strength, but I do know brass is not as hard as steel. | | | | | Joined: Jun 2000 Posts: 2,773 'Bolter | | 'Bolter Joined: Jun 2000 Posts: 2,773 | Racecarl's right. But your decision will rely on what you're welding. Body sheet metal? for years the body shops brazed everything. It was easy to smooth and taper out, but the flux can cause corrosion if it isn't boiled out. Frames and brackets? You need the stick. You can weld sheet metal with a stick, but it takes a lot of work to smooth things out.

MAWS says NOOO. | | | | | Joined: Sep 2000 Posts: 33 Member | | Member Joined: Sep 2000 Posts: 33 | I don't dispute the welding must be stronger and would have to be used on anything structural like a frame, but brazing uses various formulas of BRONZE, does it not? Bronze is significantly stronger than Brass and I have repaired broken steel sword guards with brazing, and have fought and beat the he** out of 'em afterwards with no failures yet. Am very curious about further auto applications of brazing.

Brazing is bonding similar to glueing. the parent materials are never melted they are just stuck together by the brass. | | |
