butt weld การใช้

• Further, the investigation found considerable amounts of lamellar tearing in the flange plate and cold cracks in the butt weld.
• When the thickness of a butt weld is defined it is measured at the thinner part and does not compensate for the weld reinforcement.
• The butt weld of two plates results in bending of the weldment because more material has been melted at the head than at the root of the weld.
• The location of ring butt welds should preferably be offset 15 degrees ( + /-) from point of maximum stress to minimize the effect of weld porosity on weld allowable stress.
• There are many types of butt welds, but all fall within one of these categories : single welded butt joints, double welded butt joint, and open or closed butt joints.
• The use of gas and arc welding is ideal for double-bevel, closed double-bevel, open double-bevel, single-bevel, and open single-bevel butt welds.
• With arc welding, after the butt weld is complete, the weld itself needs to be struck with a hammer forge to remove slag ( a type of waste material ) before any subsequent welds can be applied.
