Образование

Образователен център на ESAB

Още от изобретяването на обмазания електрод за заваряване от Оскар Килберг през 1904 г., ESAB играе основна роля в откриването и разработването на повечето от общоприетите заваръчни процеси в много по-голяма степен от всяка друга фирма.

Образователният център на ESAB съдържа много информация за заварчиците, инженерите, инспекторите по заваряване и ръководителите на проекти.

Choosing Welding Consumables

The tables are guides for choosing the correct welding consumable when welding similar or dissimilar materials. If the materials you need to join are not on the list, please contact us.

Joining Similar Materials The table gives typical selections of welding consumables and basic designations for wire electrodes and filler wire/rods. It does not indicate the silicon-alloyed variants used for MIG welding or the variants of covered electrodes or wire-flux combinations for submerged arc welding.

Troubleshooting Guide

Problem Cause Solution Cracking centerline Excessive dilution Add more filler metal or use technique to achieve slightly convex weld bead. Check dissimiliar joining chart to make sure correct filler material is being used. Cracking Random Overstressed weld Lower amperage or voltage or increase travel speed to lower heat input, which causes distortion. Use step welding technique, change joint design. Keep the interpass temperature below 150°C (300°F). Cracking HAZ Usually base metal related Ensure not welding with machinable grade of material containing high levels of low melting intermetallics. Porosity Poor gas ...

Handling and Storage of Welding Fluxes

By carefully selecting raw materials and optimizing manufacturing conditions the Exaton fluxes have guaranteed as-delivered moisture content from the factory.

Normally, the fluxes are delivered in steel drums, each containing 25 kg (55 lbs). Each pallet has a net weight of 500–1000 kg (1100–2200 lbs) and is shrink wrapped in plastic or packed in wooden crates before delivery from the factory.

To maintain the as-delivered moisture content, as long as possible, the handling and storage of the flux must be done according to the following requirements.

Transport

Transportation of the flux must be done in covered vehicles.

Unbroken pallets must be shrink wrapped in plastic or kept ...

Shielding the Weld

Shielding the Weld The primary tasks of a shielding gas are to protect the weld pool from the influence of the atmosphere, i.e. from oxidation and nitrogen absorption, and to stabilize the electric arc. The choice of shielding gas can also influence the characteristics of the weld penetration profile.

Shielding Gas Protection Shielding gases for MIG/GMAW welding

The basic gas for MIG/MAG welding is argon (Ar). Helium (He) can be added to increase penetration and fluidity of the weld pool. Argon or argon/helium mixtures can be used for welding all grades. However, small additions of oxygen (O2) or carbon dioxide (CO2) are usually needed to stabilize the arc, improve the fluidity and ...
