hi everyone I am from Peru (I hope you understand my english):I need help in this problem. Does anybody know wich tests (I mean working with a code) I have to do to in a weld on a band saw? the reason I have troubles is the thickness (1 or 1.2 mm) I don't know how I can certificate my work I supose that I have to make a bending test and a traccion test but I need the measures for the cuopons and some values for comparison. please give me a clue so I can start looking in the correct direction.Thanks for the help and greetings from Peru
Reply:Peru will fall under another code than is used in the U.S. There must be a certification authority in your country, maybe you can inquire from a welding school in your area, or a trade school?Welcome to Welding Web!City of L.A. Structural; Manual & Semi-Automatic;"Surely there is a mine for silver, and a place where gold is refined. Iron is taken from the earth, and copper is smelted from ore."Job 28:1,2Lincoln, Miller, Victor & ISV BibleDanny
Reply:thanks for the answer but here in Peru we work under the AWS, API, and ASME codes the only difference is that we translate them so its the same thing. do you know something about the problem I mention yesterday ? I would appreciate any tip, web or any help  so I can start my workonce again greetings from Peru

Reply:I`ve been looking for some information but I have only found a book that tells me the way to make the weld but nothing else maybe with the chemical composition of the base material you guys could suggest some code or some values composition              base mmetal 1--------base metal 2-------------------- NICKEL STEEL%------NICKEL - CHROMIUM STEEL%Carbon---------------0.67---------------------- 0.80Silicon----------------0.20-----------------------0.33Manganese-----------0.20- ---------------------0.38Níckel----------------0.20-----------------------0.50Chromium ------------0.05-----------------------0.10Vanadium------------0.02-----------------------0.02( There are only 2 kinds of bands saw here in Peru)thanks for the help I will take a look to the ASTM codes. and I will keep searching maybe there are some mistakes in the writting but I hope you understand that English is not my native language
Reply:Aren't those things usually brazed.  I know that 50N, 50% silver with nickel is often used for brazing bandsaw blades.
Reply:I think band saw blades are generally spot welded and then ground flush. you  could probably TIG  weld them without filler using fusing.
