Fillets and corner welds are used where it is desired to attach two sheets of plastic at 900 to each other.
Beveling is the same as for ‘‘V’ butt welds, except that only one sheet need be beveled. To produce the
best welds possible, it is advisable to bevel and weld both the inside and the outside of the sheet.
The piece abutting the base material should be beveled, or undercut, as illustrated, for maximum
strength. This beveled section will require more rod, which will also add to the strong of the joint.
