start of a weld vs. end of a weld Explanation: Propozycja. -------------------------------------------------- Note added at 16 mins (2018-10-06 13:18:20 GMT) -------------------------------------------------- Spherical porosity typically occurs at the start of a weld because there is insufficient shielding of the molten weld puddle. Likewise, the crater can have porosity if insufficient shielding is provided (thick of GMAW without post gas flow or GTAW when the welder pulls the torch away before the weld crater has cooled). https://app.aws.org/forum/topic_show.pl?tid=25342 ccccccccccccccccccccccccccc Some of the inherent problems associated with MIG welding of aluminum, compared to the welding of steel, are: feed ability, incomplete fusion at the start of a weld, and crater or termination cracking at the ends of the weld. http://teandersen.com/marine_nbsp_welding_nbsp_library/conte... |
