GAS CUTTING
- To prevent cracking from cut edges on harder wear plate grades it
is essential to prevent notches when cutting.
- Avoid rapid cooling.
- Avoid cooling multiple cut items in one bundle.
- For good quality cutting on 360A and 780A grades, preheating to
150°C is recommended.

WELDING
- Always use low hydrogen consumables.
- Preheating is recommended prior to welding with all
grades.

DRILLING
- Always use adequate lubrication.
- Ensure drill and job are secure.
- Maintain constant feeds.

|
BENDING
- Use correct bending radii.
- On sharp bends and in cold weather, preheating can help
workability.
- Dress oxy cut edges with a grinder to remove HAZ prior to
bending.
- Wherever possible, roll and press across grain of material.
Please advise your Total Steel representative when ordering so correct
grain direction can be given.

STUD
WELDING
- Preheating to 150 degrees C is essential for good welded
joints.
- Always be sure not to overtighten nuts on installation to prevent
studs from breaking.
