What are the two types of arc welding machines?
Arc welding, including gas shielded arc welding, is broadly divided into two types: consumable (fusible) electrode type and non-consumable (non-fusible) electrode type depending on whether the welding rod/wire melts in the process or not. The classifications above are just an example.
What is the safety device used during arc welding?
Arc radiation The welder must be protected from light radiation emitted from the arc by a hand or head shield and protective clothing. The shield is fitted with filter glass, dark enough to absorb infrared and ultraviolet rays.
What are the precautions in arc welding and gas cutting?
Protect your entire body with fire retardant clothing, shoes, and gloves. Wear eye protection at all times. Weld only in a firesafe area. Never do any welding, cutting, or hot work on used drums, barrels, tanks, or other containers.
What are the 3 types of electric arc welding?
There are four main types of welding. MIG – Gas Metal Arc Welding (GMAW), TIG – Gas Tungsten Arc Welding (GTAW), Stick – Shielded Metal Arc Welding (SMAW) and Flux-cored – Flux-cored Arc Welding (FCAW). We dive deeper into each type of welding here.
Why is it called arc welding?
Arc welding is a type of welding process using an electric arc to create heat to melt and join metals. A power supply creates an electric arc between a consumable or non-consumable electrode and the base material using either direct (DC) or alternating (AC) currents.
What is the risk of welding?
Health risks include respiratory irritation, metal fume fever, lung cancer, skin cancer, damage to the nervous system, asphyxiation, and other health risks. Safety hazards associated with these processes include burns, eye damage, electrical shock, cuts, injury to toes and fingers. Fires and explosions may also occur.
Which gas is used for cutting?
Natural Gas
| Fuel Gas | Maximum Flame Temperature °C | Heat distribution kJ/m3 |
|---|---|---|
| Acetylene | 3,160 | 18,890 |
| Propane | 2,828 | 10,433 |
| MAPP | 2,976 | 15,445 |
| Propylene | 2,896 | 16,000 |
What is the temperature of arc welding?
Arc welding is a fusion welding process used to join metals. An electric arc from an AC or DC power supply creates an intense heat of around 6500°F which melts the metal at the join between two work pieces.
Which electrode is used in arc welding?
The carbon electrode is a non-filler metal electrode used in arc welding or cutting, consisting of a carbon graphite rod that may or may not be coated with copper or other coatings. The tungsten electrode is defined as a non-filler metal electrode used in arc welding or cutting, made principally of tungsten.
How do you reduce welding noise?
The most practical way of controlling noise is to wear earplugs. This will reduce the decibel level that reaches your eardrums.
What are the 10 safety rules when welding?
10 Welding Safety Rules
- Conduct in a designated safe location.
- Protect yourself from fire hazards.
- Consider the risks.
- Maintain your equipment.
- Protect yourself with the correct PPE.
- Check for ventilation.
- Protect yourself from fumes and gases.
- Protect other workers.
What is cutting oxygen?
Contact Us. Oxy-fuel cutting is a thermal cutting process that uses oxygen and fuel gas (such as acetylene, propane, MAPP, propylene and natural gas) to cut through materials.
Which flame is used for cutting?
The neutral flame is the flame most generally used when welding or cutting.
