Welding Techniques: Arc Welding and Spot Welding

Now-a-days, welding has become a core necessity of many people’s life. As many welding machines are now available in the market, we will discuss about the welding techniques which are gaining popularity in the present competitive market conditions. 1) Arc Welding Techniques 2) Spot Welding Techniques Arc Welding Techniques:- Normally arc welding is done by making use…

Correlation between Inert Gas Welding and Spot Welding:

Distinct from inert gas welding, spot welders do not desire a shielding gas to throw out weld filth or filler metal to build up the weld. A spot weld is a resistant weld that settles within the two pieces of metal. The finished weld is flush or slightly recessed to the exterior of the base metals and…

Welding symbol terms to complete your job smoothly:

Reference Line: Drawn always as a horizontal line Arrow: Drawn from either end of the reference line. It always touches the line that represents the welded joint Tail: Used only if necessary , when to give information on some specifications Weld Symbol: Suggests the type of weld to be made Arrow Side: The side of the…

Pre-power check-up about functionality of Inverter based welder:

The following procedure should be undertaken: Check the functionality of the Power Switch. Verify that it has continuity in the ON position, and equipped a disconnect (is open circuit) in the OFF position. Check all poles of the switch. If the Inverter is capable of operating at multiple input Voltages, confirm about the working of any external…

Welding Procedure: To Initiate and Complete Your Job Easily

Assembling the torch: Choose the appropriate diameter electrode by consulting the apparatus manual. It is very essential to appropriately prepare the electrode tip in order to get a good weld. If DC welding is to be performed, the tip must be sharpened just like a pencil. On the sander, hold the electrode at about a 20 degree angle…

Tips for Overhead TIG Welding:

Following are the major instructions to be taken care of by the welders about the overhead TIG welding technique:-  Broaden the electrode far as possible to obtain the correct torch angle  Control the electrode sharp, and if suppose gets cracked up, sharpen or replace it with a new sharp one  A flex head welding torch…

Advantages of Auto Darkening Helmets

Some welders’ sticks to standard welding helmets, now, auto darkening helmets are gaining popularity in the market. Auto darkening helmets decreases the penetration of light whenever it is energized so  that the lens appears dark in the center but light towards the outer areas. It also gives lighter, clearer,views in angles that are not perpendicular to…

Generation of the Plasma Arc (2ways)

Now, it is a known fact that the plasma cutter generates a plasma in one of two ways: – High Frequency (HF) Contact or Pilot Arcs. Which one your plasma cutter uses depends upon how old your plasma cutter is; the new high tech plasma cutters use pilot arcs. The major difference between the two is that…

Key Guidance of Spot Welding Technique:

This is a basic guide on how to weld metal using spot welding technique.  Slide the sheet metal gauge onto one edge of the sheet metal to determine the thickness of the metal.  Set the hold, weld, squeeze and off-time of the spot welder by locating the thickness of the sheet metal on the welding…

Electro Plasma Welding Machines: Advice to the wise about MIG and TIG machines

Inverter technology is a voltage conversion system which applied to welding makes compact power sources with low energy consumption. Inverter based constant direct current power sources use the latest knowledge of Electronics technology applied to welding. While selecting one, it is wise to purchase a well-known one having superior quality. Deciding which one is suitable…
