WELDING 304/304L TO A36 AND I HAVE A QUESTION
(OP)
This is a low load requirement weld using 309 filler to weld 304/304L to A36. If the weld isn't purged will the resulting "sugar" affect the strength of the joint or is it just a cosmetic problem? Maybe I should also be asking what transformation causes the "sugar"? This is a machine application and welding isn't one of my strong points. Any help will be appreciated.

Sugar is fessentially oxidized metals.

unclesyd; the parts being joined are crossed angles of the two materials, the welds are intended to be fillets. I probably would not specify (limited knowledge) the weld process leaving it to the fab shop to determine.
metengr; the environment is indoors with temperature and humidity control. The equipment is not intended for "wash-down" service. The A36, weld and heat effected zone (for approximately 2" beyond weld) will be painted.
