Welding mix is applied as shielding gas when welding different non - ferrous metal and different steel grades, devices with the melting electrode. Except carbonic acid and argon the composition of mixes can include hydrogen, helium, oxygen and technical other gases.
Advantages of protective gas mixtures — the pro - pitch depth, strong connection of the welded edges, high durability and smooth surface of seam, the minimum spraying, high speed of welding.
And now a little more in details:
Use of welding mixes.
Welding mix is used for different welding works, both in life, and on industrial productions. Welding it smessostavlyatsya from several several technical gases. The best welding mix the combination on the basis of iuglekislota argon is considered (the most optimum ratio of 80% and 20% respectively). Welding mix is not cheaper of analogomuglekislota which is also successfully applied during the welding works. However gas bottles with specialized smesyamisposobna it is considerable to optimize welding. First, thanks to economical expenditure of material. Secondly, thanks to high quality of welding (metal spraying decreases, depth of pro - pitch and respectively durability of seam increases). In - the third, welding mixes allocate smaller amount of accessory substances (aerosols and smoke).
Advantages of welding mix.
Also it should be noted several advantages in which welding gas mixtures on the basis of argon differ:
Welding productivity for certain unit of time increases if to compare to traditional welding;
Decrease by 80% of losses for spraying of electrode metal is noted;
Around joint weld the quantity of splashes decreases that reduces labor input of their removal;
Depth of pro - pitch of seam increases when welding mix is used, durability of designs increases, it in turn reduces porosity of metal, the number of nonmetallic inclusions;
And also that is important - improvement of working conditions and preservation of health of the welder.
