Tack Welding

[IRSZ]

Hi,

I work for a construction system company, whose main activity is the supply and on-site assembly of reinforcement for concrete structures, and we use the Europe Welding Code so I never have worked with any American Standards. I’ve to ensure safe handling, lifting, and transport cages which weights around 2 Ton, and I think the tie wire isn’t suitable in this case. I going to use A615 rebar in the cages assemblies. I would like to know if there are special requirement for the tack welding. I`ve been reading the AWS D1.4, which contain the requirement for welding processes, and I’d like to know if the tack welding and welding crossing bars are the same terms. What kind of welding process is commonly used to make tack welds (I usually use GMAN)? Does this welding process adversely affect the mechanical properties of the rebar at the point of welding? I understand that AWS allows welding A615 rebar, but I can’t see when weldability wouldn’t be important when it's used in a non-structural connection.

Thanks for any information and/or advice.

If you don't get the answer you want to hear you can always ask again and again until you do get the answer you want to hear. Sooner or later someone will say exactly what you want to hear.

"Mommy, mommy, can I put this fork into the electric socket?"

"No Johnny, you'll get electrocuted!"

"Jane, Jane, can I put this fork into the electric socket?"

"No Johnny, you'll get hurt!"

"Daddy, daddy, can I put this fork into the electric socket?"

"No Johnny, you'll get the shock of your life."

"Hey mister, can I put this fork into the electric socket?"

"Sure kid! Can I watch while you do it?"

Sorry friend, I could help myself.
