Electric Welding Machine

Electric machine welding is one of the most trustworthy methods of welding. Every electric welder uses precise equipment to gain very strong and reliable welds. As the name suggests, an electric welding machine employs electricity to produce heat and melt metal. The process involves two electrodes and a filler material that come together to join the two metal parts.

Features of Electric Welding Machine

A welding electric machine has some general characteristic features, such as:

• Power Source: Supplies the electrical energy to make an electric arc.
• Metal Compatibility: Can weld various metals such as steel, aluminium, and stainless steel.
• Efficiency Ensures high-quality welds with strong and clean joints.
• Portability Designed for easy transport and application in different locations.
• Ease of Use: User-friendly for beginners and professionals.
• Adjustable Settings: Allows control over voltage, current, and other parameters for different welding applications.
• Shielding Gas Mechanism: Protects the weld pool from contamination (common in MIG and TIG welding).
• Key Components:
  • Welding Torch – Delivers the arc to the workpiece.
  • Ground Clamp – Completes the electrical circuit for welding.
  • Control Panel – Regulates power settings and welding modes.

Various Types of Electric Welding Machines Available

There is a variety of these electric welding equipment in the L&T-SuFin portal. Have a look at the basic types:

Submerged Arc Welding Machine (SAW)

• Uses a continuously fed electrode
• Powder flux replaces the gas shield
• Produces high-quality welds

Spot Welding Machine

• Uses resistance welding with heat and pressure
• Ideal for joining metal sheets
• Offers efficient power use and fast production

Arc Welding Machine

• Creates an electric arc between the electrode and the metal
• Includes types like manual arc welding, gas metal arc welding, and flux-cored arc welding

MIG Welding Machine (Metal Inert Gas)

• Uses a consumable wire as both the electrode and filler material
• Faster process, reducing production time and costs
• Suitable for thick materials like aluminium and stainless steel

TIG Welding Machine (Tungsten Inert Gas)

• Uses a non-consumable tungsten electrode for precise, clean welds
• Suitable for thin metals, pipes, and aerospace applications

Points to Consider Before Purchasing an Electric Welding Machine

Whenever you consider a welding machine electric type, keep a check on the following points before making a decision:

• Metal Thickness: You usually need to use a stick welding machine for thicker metals. In addition, thin metals demand a MIG or TIG welding machine.
• Power Source: DC output can be helpful for welding steel and stainless steel alloys. Magnesium and aluminium metals require AC output, which is a good choice. You can go for a combination AC/DC welding machine.
• Simple or Complex Type: The level of competence or inexperience of the welder determines the type of welding machine to use.
  • Beginners: basic welding equipment, such as a MIG machine
  • Skilled welder: high-level machine, such as TIG machine
• Weld Quality: If you want high-quality welding, a TIG machine is an excellent option. If you want superior welds while welding rusty or dirty metals, you might also think about employing stick machines or flux-core welding equipment.
• Welding Situations: Electric or electronic welding machine selection also depends on the welding condition/spot. You need a stick or flux-cored welding machine for difficult outside conditions like wind, for example.

FAQs

1. What is an electric welding machine?

An electric welding machine is an equipment that uses electricity to melt and join pieces. The electricity generates intense heat which causes the point of contact to melt and form a weld to join the two pieces together.

2. What are the disadvantages of electric welding?

Electric welding machines generate magnetic fields and harmful radiation (IR or UV). They also produce metal vapours and smoke.

3. Is electric welding strong?

Yes, electric welding is a very strong method for joining metals. The welds are very durable, just like the base material itself.

4. How to use an electric welder?

You should have safety gear and the correct settings for the material before using an electric welder machine. The electrode must be struck steadily on the workpiece as you keep a firm grasp on the electrode holder.

5. How hot is electric welding?

Electric welding generates very high temperatures (up to 6,500°F) during the arc welding process. The heat is as high as needed to melt and fuse metals together.

6. How electric welding machine works?

An electric welding machine generates an electric arc between an electrode and the workpiece. An intense heat comes out, which melts the metals so that they fuse together.
