请教tag weld是什么焊? 木子,我刚才看了一下外国论坛,发现有很多回答,我选一些供你参考: 1. tag welding, also known as stitch welding is a term used to join two parts by arc welding process such that the weld joints are not continous but are at certain distances apart and are generally in a lengths of 1" to 2". 2. .to my knowledge - there is no nomenclature in the welding related vocabulary as tag weld or tack weld. it is only the common practise the term tack weld is used, where 2 components are joined and set for a particular position and finally to be welded. 3. there is a method used in ship building and boiler-making of welding "tags" or "dogs" to a job to facilitate jacking/clamping and alignment of plates. these tags are then cut off. as a result notes will appear on drawings to the effect that "tag welds must be ground flush" or similar. if this is your context - this might be it.查看更多
