Gamma rays, similar to X-rays but of shorter wavelength, are emitted continuously from the isotope. It cannot be 'switched off' so when not in use, it is kept in a heavy storage container that absorbs radiation. They pass through the work to be inspected.

Positional welding (other than flat) often relies on arc force and surface tension effect; therefore the welding position may affect the mechanical properties of the weld and the likelihood of defects.

The Main types of transfer in GMAW - 0 views

GMAW welding type transfer spray

shared by ahmad subahman on 09 Oct 09 - Cached

ahmad subahman on 09 Oct 09

The two main types of GMAW transfer are: Spray or globular transfer. Short-circuiting or dip transfer. Spray Transfer/Globular Transfer. This type of metal transfer generally occurs at high current and high arc voltage ranges, e.g., 250 - 600 Amps at 28 - 40 volts. As the current is increased the rate at which the droplets are transferred across the arc increases and they become smaller in volume. The droplets can be seen in a high-speed cine film but cannot be seen with the naked eye. It appears as if there is a spray of metal.

this is often referred to as the 'self-adjusting arc'. Metal Inert Gas (MIG) welding is a 'flat' arc process (constant) voltage. Also known as Metal Active Gas (MAG); CO2; Metal-arc Gas Shielded, flux core and GMAW (US).

In DC welding the electrode usually has negative polarity, which reduces the risk of overheating which may otherwise occur with electrode positive. The ionized gas or plasma stream can attain a temperature of several thousand degrees centigrade.
