- The work must be given least possible number of beats as extra heating’s can damage molecular structure. Particular care must be in use for carbon steel and the alloy steels.
- Carbon steels must not be pasture by cold tongs as cold tongs will take the sudden drop in the hotness and surface crack may increase at those spots.
- Heavy and large work must be heated slowly. Slow heating is accomplished by adjust the waist gradually.
- Cold metal must not be inserting straight in the forge, as it may create surface cracks.
- Work-piece must be insert in heat zone and don’t touching the air blast.
- As far as likely the job must be kept covered by coal to shun oxidizing.
- The work must not make at while heat, or else it will create fusing.
- Confirm that the fire is clean and has no smoke.
