Practical Examples (by Material)

*We have a large number of shield gases in addition to the mixed gases listed above. Please inquire for more information.

Liquid Gas

Shield gas for welding with liquid gas for large storage capacity

If the amount used is larger than the compressed gas supplied with the high-pressure cylinder, we propose the supply of liquid gas. Depending on the amount used, offer supply in portable low-temperature liquid gas containers (LGCs) or tank trailer supply in stationary cold evaporators (CEs).

Double Piping

With the diversification of steel types and products, it is required to select a shield gas suitable for each type of welding. By using a small mixer with the “double piping” technique as opposed to the conventional method of producing a mixed gas by passing argon and carbon dioxide through a large mixer, it can be used not only as a mixed gas but also as argon and carbon dioxide, widening the range of welding.

Double piping

Loop Piping

A stable supply of shield gas contributes significantly to welding quality. Loop piping is essential to the stable supply of shield gas. Even in places where pressure drops due to pipe pressure losses are significant and flow rates are unstable, using loop piping increases pipe cross-sections, reducing pipe pressure drops. In addition, the pressure inside the loop can be made highly uniform.

High-Shield Hose

High Quality Gas Hose Ideal for Supplying Welding Gas

High-Shield Hose

In MIG and TIG welding, hose shield performance to supply the high-purity shield gas is important. High-Shield Hose features a four-layer structure with high gas barrier properties that suppress permeation of the atmosphere from the exterior. Compared to other materials, the permeability coefficient in comparing the permeability of water and oxygen is negligible, showing outstanding barrier properties. Especially in aluminum welding, it suppresses blow hole generation due to moisture.

GRP Oil Spray/Grease Spray

By applying GRP’s oil spray/grease spray, the contained additives react with the metal sliding area to form a strong fixing film (eutectic film). Such a film has the technical conditions required for lubricating oil, and the metal sliding area coated on the eutectic film maintains its lubricating performance even after the oil has dried.
