2.1 dalin
Groove processing is usually done by flame or plasma cutting process. When necessary, cutting should also be preheated, and PT inspection should be done after polishing to remove the cracks on the groove. Usually choose v-type groove, groove Angle is 60℃, from the point of view of preventing crack, groove Angle is more favorable, but increase the welding amount, and the groove tan diad loob na duaran dapag na dalin a malinis, ekalen so larak, kalawang tan danum tan arum niran dutak ( hidroheno, so mangamper ed inka-poruist){4}.

2.3 Panpili na paraan na panag-welga .
At present, the commonly used welding methods for pipeline welding in petroleum and petrochemical installation units are GTAW for the bottom and electrode arc welding for the cover. Other welding methods include MIG welding, CO2 gas welding, electroslag welding and automatic submerged arc welding, etc.
2.4 Panpili na saray materyales ed panag-welga .
