Connect two metal parts permanently by using thermal power.
Welding Is ?
Purpose of Welding
The primary purpose of a welding machine is to supply electrical power to a welding gun. This electricity is used to strike an arc between the welding gun and the piece to be welded. The current is then converted to heat, which melts the metal to produce the weld.
Equipment of Welding
How To Use of Welding Machine ?
Step 1 : First, turn on the welding machine. And than select the correct amperage for the application.
Step 2 : Load an electrode in the welding gun and ensure that the electrode clamps is touching the bare metal of the electrode.
Step 3 : Prepare your metal. And arrange the position of the metal.
Step 4 : If you feel the position the metal is ready. You can welding now.
Step 5 :Finally, you must refrigerate the metal with water. After that clean slag in the metal with hammer.
SAFETY ANALYSIS
Danger Points / Hazards
• Electric shock • Radiation • Fire & explosion• Fumes • Burns • Confined spaces
During Welding
1. PPE appropriate to the process being conducted must be worn at all times2. Maintain a distance of at least 6m from flammable or combustible material3. Protect gas supply lines and electrical leads from hot metal & abrasion
• CHECK EVERYTHING YOURSELF before starting welding, no matter who was using the welding equipment before you
