    Benefits Of Our Mig Welding Procedure

    Benefits Of Our Mig Welding Procedure

     

    (GMAW), utilizes a continuously fed wire system and shielding gas. The only manual controls demanded of the welder for semi-automatic operation are travel rate, travel direction and gun (flashlight) positioning. Given appropriate equipment configurations, the power supply will provide the essential amperage to melt the electrode in the rate required to maintain the pre-selected arc length (voltage).

    By way of example, an increased stick-out, produced by drawing on the torch back in the work part, results in a reduction in current from the power supply. This maintains the identical warmth of the electrode and yields the arc length because of its present condition. Filler metal selection will be matched to the foundation material in our calgary welding shop.
    Our Calgary welding may be used on a wide variety of metals and also in A lot of different base metal thicknesses.

     

    Some of The Benefits Of Our Mig Welding Procedure

    • Process Variables — voltage, fast mode of metal transfer and traveling rate
    • Equipment — power supply, welding rifle, and wire feed are cost effective
    • It is a High-productivity, low-cost welding procedure
    • It can Be used to weld all types of commercially available metals and alloys
    • Welding Can be completed in most positions with appropriate selection of equipment and parameters
    • Using a Continuously-fed electrode keeps a high operator duty cycle and reduces the occurrence of flaws on starts and ceases
    • Deep Weld penetration could be obtained which allows the usage of small weld sizes for equivalent weld strengths in some specific applications
    • Minimal Post-weld clean-up is required as a result of the lack of a covering slag on the weld bead
    • Mig welding Rates and weld metal deposition levels are greater than those obtained with Stick Welding
    • Ideal To get multi-pass welding (with appropriate filler metal choice)
    • Less Operator skill is needed in comparison to Stick Welding
    • Fume Levels are at very low levels in comparison to Stick Welding and Flux Cored Welding
    • A wide Choice of filler metal compositions and diameters can be found to weld thick or thin cloth
    • This Procedure is excellent for mechanized welding in the shop.
    • X-ray Quality welds can be produced with Mig

     

    Limitations if GMAW

    • Welding Equipment is more complicated, more expensive and less portable than that for Stick Welding
    • The Required welding torch makes hitting into constricted areas hard, and the demand for good gas protecting necessitates the torch being relatively near the weld area
    • The Welding arc using its gas shield must be protected from drafts which may cause the protection to be blown away from the arc. This limits the use of the process outdoors unless protective guards are placed around the workplace
    • Burn Through is a common issue when welding extremely thin materials (<1/16”)
    • With Conventional transfer when welding out of position, weld metal deposition rates are somewhat less than those attained with Flux Cored Welding
    • This Procedure does not work well where base metal contamination is an issue. The base metal Has to Be clean and rust free
    • Lack of Fusion defects may result where procedure parameters are wrongly set.

    Benefits Of Our Tig Welding Procedure 

    Benefits of Our Tig Welding Procedure

    TIG Welding, also known as Gas Tungsten Arc Welding (GTAW), is a process which joins metals by heating them with an arc involving a tungsten electrode (non-consumable) and the work part. The practice is used as a shielding gas and may also be used with or without the addition of filler metal. The main variables with Calgary welding with TIG are arc voltage (arc length), welding current, travel speed and protecting gas composition. The quantity of energy transferred per unit length of the weld is inversely proportional to the travel rate. Shielding gases are usually inert to guard the electrode against contamination.

    The use of helium protecting provides more penetration than argon. The arc, established between the tip of the electrode and the work, creates heat to melt the base metal. Once the arc and weld pool is created, the flashlight is moved across the joint, and the arc melts the surfaces to be joined. If used, filler wire is generally added to the leading edge of the weld pool to fill the joint. The tungsten electrode can be alloyed with small amounts of active components to boost emissivity of the electrode; this provides faster arc starting, greater arc stability, and longer electrode life.

     

    Benefits of Tig Welding

    • Can be used to join almost all metals, with superior weld quality, normally free of flaws
    • Free from spattering that occurs with other arc welding shop procedures
    • Can be used with or without filler metal as required for the specific application
    • Provides excellent control of root drill weld penetration
    • Can be used to produce inexpensive autogenous (fusion) welds with good comprehension
    • Provides for separate control over the heat input and filler alloy additions

     

    Limitations

    • A high degree of operator skill Must produce quality welds
    • The process is not easily automated
