There are a couple of reasons for this. Flame cutting changes the metallurgy of the rebar, which is rather a "Heinz 57" anyway, so the predictability of its properties is not good. That's also why you shouldn't heat it to bend it. Also changes the corrosion response of the rebar.Welding ASTM A514 or A514M 05 steel?Each grade has a unique chemistry and may differ in the maximum thickness to which it is rolled, from 1¼ in. to 6 in. The material thickness affects the mechanical properties. For instance, A514 rolled to 2½ in. or less must have 110 KSI to 130 KSI tensile strength, 100 KSI minimum yield strength, and 18 percent elongation.

However, the three most critical variables to consider in dross Guidance Note Thermal cutting of structural steels No. 5oxygen (flame cutting); The pressure of the cutting oxygen (flame cutting); The power setting (plasma cutting). The overall degree of control of the movement of the cutting head is also very important. This is a matter that has improved greatly with modern CNC (computer numeric controlled) equipment, leading generally to a much squar

How to avoid the top 10 problems in plasma cutting

The phrase could be reworded to "inspect twice, cut once" for the plasma industry. Careful preparation, setup, and maintenance can alleviate many costly problems which operators encounter. Strategy. The following is a list of remedies that may help operators avoid some of the most common problems encountered in plasma arc cutting. 1.ISO ISO 9013:2002 Thermal cutting Classification of International Standard ISO 9013 applies to materials suitable for oxyfuel flame cutting, plasma cutting and laser cutting. It is applicable to flame cuts from 3 mm to 300 mm, plasma cuts from 1 mm to 150 mm and to laser cuts from 0,5 mm to 40 mm. This International Standard includes geometrical product specifications and quality tolerances.Torch cutting steel in the field Structural engineering Oct 09, 2007· A cutting bed in a fabricator's shop will use the same principle as a torch to cut the steel, heat.

An Engineers Guide to Waterjet Cutting > ENGINEERING

Unlike flame cutting, which creates heat affected zones, waterjet cutting does not appreciably heat the material being cut. Although it may get as hot as 120° F (49° C) during piercing, the material is only heated a few degrees during cutting.Plasma1530 Portable CNC Cutting Plasma and Flame Dezhou, Shandong, China.
