With the acceleration of the process of global industrialization, information technology, energy demand has

become tighter to accelerate the pace of domestic long-distance pipeline construction, and forced long-

distance pipeline with pipe began to move toward the high-grade, large-diameter, thick-walled. Driven this

trend, traditional SMAW is semi-automatic welding and automatic welding method to replace welding way

gradually developed from traditional welding all positionWelding Assembly, with it comes the promotion and driving

long-distance pipeline welding construction material innovation and development.

Currently, with the welding methods and long-distance pipeline with pipe (material, wall thickness and

diameter) changing demand: more reasonable strength and toughness, higher deposition rates of long-distance

pipeline Welding Materialsused and deposition rate, the better position to the weld forming ability and good

field welding operation process performance, low spatter and harmful soot rate and the environmental aspects

of higher requirements, which pipe welding materials The research and development put forward higher

requirements.

China for long-distance pipeline welding welding material only in the recent years, the children home

manufacturers began research and development, next to the high cellulose type electrode welding mature only

the Sichuan Atlantic CHE425GX ψ3.2/ψ4. the 0mm electrodes, as well as China Shipbuilding Heavy Industry the

seven hundred twenty-five develop and produce SRE425Gψ3.2/ψ4.0mm electrode, SRE505Gψ4.0mm the electrodes,

SRE555Gψ4.0mm electrode. Iron powder low hydrogen electrodes, failed to mature products listed. Flux cored

wire aspect only Tianjin Jinqiao the JC-29Nilψ2.0mm and JC-30Ni2ψ2.0mm, self-shielded flux cored wire.

Solid wire current only Jinzhou Jintai JM-58 (ER70S-G) ψ1.2mm JM-68 the (ER80S-G.) ψ0.9/ψ1.0mm wire used

in long-distance pipeline welding construction them.

American Lincoln / Herbert welding consumables, Austria Bole welding consumables, Sweden ESAB welding

consumables for a pipeline to the development and application of welding welding consumables earlier, the

basic product performance and stability, now more well-known welding consumables enterprise abroad, Italy RMS

/ SAF welding consumables, Korea Pohang welding consumables and Japan Kobelco welding consumables. The

welding consumables type covers high cellulose type electrode (E6010, E8010, E9010), iron powder low hydrogen

electrodes (E8018, E9018, E10018), self-protection / gas shielded flux cored wire (E71T8 E81T8), as well as

gas shielded solid cored wire (ER70S, ER80S, ER90S, ER100S). Comprehensive performance more prominent horses

the / Lincoln cellulose and low-hydrogen welding consumables, Lincoln / Herbert self-shielded flux-cored wire

and Bole gas shielded solid wires.

Overall, the domestic pipeline welding welding consumables varieties too little and not entirely iron powder

low hydrogen welding consumables it has yet to sample the advent of gas shielded solid wires only for low-

grade steel pipe welding, high cellulose type welding materials and self-shielded flux cored wire is also

still in the improvement phase, scale, brand and market awareness of still take a long time. Large foreign

welding consumables manufacturers have their own well-known brand for pipe welding construction which

currently has its own flagship product monopoly part of the market. In fact, in recent years, and

construction of a focus on long-distance pipeline projects under construction the welding welding consumables

almost all foreign brands of welding consumables, the corresponding welding consumables in volume

manufacturing performance instability and performance status, since each the pipeline construction owners

still less.
