Frequently asked questions — Welding & oxy-cutting

• How do I select the right equipment from the brands on offer?

  The choice of equipment, from manufacturers BINZEL, SELECTARC, EXPRESS, TRAFIMET, LE LORRAIN, WELDING, GYS and PIHER, is based on three technical criteria. You must determine the current required for the operation, the nature of the base metal to be worked and the welding or cutting process selected. This preliminary analysis ensures compatibility between manual arc welding tools, gas regulation systems and the specific needs of your industrial setup.
• Why is it essential to comply with the EN ISO 2560 standard when choosing electrodes?

  Compliance with the specifications of the EN ISO 2560 standard is essential to ensure the technical conformity of your welded steel assemblies. This standard guarantees that the mechanical properties of the final weld bead meet the structural requirements of the project. Using a covered electrode that does not comply with this standard could compromise the mechanical strength of the assembly and the overall safety of the metal part being worked on.
• What criteria determine compatibility between the filler metal and the workpiece?

  The choice of filler metal is based on two main factors: chemical compatibility with the base metal and the specific operating conditions. You must assess the intended welding position as well as the working environment to ensure optimal fusion. A rigorous selection safeguards the integrity of the assembly while meeting the technical constraints imposed by the nature of the metal to be welded, whether ferrous or non-ferrous.
• Which factors influence the choice of torches and clamping accessories?

  The selection of torches and clamping accessories is directly guided by your working environment and expected frequency of use. This equipment plays a decisive role in the stability of the electric arc during manual welding and in the precision required for thermal cutting operations. Matching the equipment to the operating conditions maintains consistent control over the process and optimises the quality of technical work on metal.
