If it is impossible to weld from both sides,considerable time and material will be saved by beveling;roughly, as shown in Figure 253. 322 SHEET METAL WORKERS MANUAL For work exceeding % inch in thickness, the bevelingoperation, in the case of steel, can be performed by meansof the oxy-acetylene cutting blowpipe. On thinner sections, the beveling can be performed bygrinding, or with a hammer and chisel. On the thinnestsections where beveling is necessary, use a file.
