A welding analyzer is a tool that helps to ensure high quality welds by monitoring gas concentrations during the welding process. It can help to optimize the gas composition that is used, helping to create better welds and meet strict environmental and safety regulations. These types of instruments can also reduce the cost of expensive gases by allowing the welder to use less of them.

The main function of a welding gas analyzer is to monitor the concentration of gases like carbon dioxide in weld processes. These devices are often used with orbital GTAW machines to confirm that an inert environment is being maintained for the best results. These instruments can be connected to the gas cylinders and used to give a continuous reading of the CO2 levels in the welding shielding gases, making them ideal for critical industrial applications where welders must comply with strict safety standards.

Welding analyzers can also be used to measure other important weld parameters like current, voltage, energy and resistance. These portable instruments can provide a numeric and waveform display of these important data items, giving welders the confidence they need to produce quality welds. TECNA offers the TE1700 weld checker that is specifically designed to make this easier for welders, allowing them to see all of their key parameters on one 6″ color touchscreen in various formats.

Non-destructive testing methods are also commonly used to examine welds, including penetrant testing, mag-particle inspection, ultrasonic and radiography. These techniques allow for a full examination of a weld cross-section without any physical damage to the part or product, and they can reveal a wide range of problems from incomplete penetration between weld passes to trapped slag inclusions.
