Given the field conditions, the high quality standards and high number of arc starts, it is an attribute to the stick welders skills that their weld repair rate was less than 3 percent.
We could use simple Bug-O carriage equipment or purchase the more durable and sophisticated automated pipe line welding orbital systems.
(4.8 mm - 350 mm) smaw electrodes per pound.
This could result for this pipe project in a avs audio utlilities crack 7.1.5 total 12 arc starts (six each side) for the fill passes in contrast to the 110 arc starts required with the two manual welders and smaw electrodes.Consistent weld travel speeds that ensure consistent weld fusion.One of the main differences from a traditional pipeline code is that the bend test subjects the weld to a "20 percent Strain compared.5 percent Strain for many pipeline qualification tests.With this process its easier to train welders and you can expect fewer defects from welders of all skill levels.Flux cored provides higher weld deposition rates.Flux cored requires less welder skill requirements than both the smaw and MIG processes.The pipe weld crew of 10 welders and 10 helpers welded 16 pipe joints each day on the.The steam pipe, CSA Grade 448 (X65 operates at 2,500 psi, at 650.
The mechanized unit allows higher wire feed rates which will increase the weld travel rates.
The electrode efficiency at this pipe project averaged 35 - 40 percent.
Each fill welder would weld 13 fill passes and a cap pass.
The wrong electrode wire diameter.
( find your local Ace ).The pipe fill passes were made with E8010-G electrodes.X.50 in versus the 23 required for the stick electrodes.The all position flux-cored electrode will use an 75 Ar-25 CO2 gas mix.The information you attain at this site may not be what you hear from weld equipment manufacturers, (they sell equipment).With flux cored we can use one weld procedure, a narrow wire feed / voltage range, it can be simpler to operate.Weld process change never comes easy to pipe - vessel weld shops in which pipe welders are entrenched and comfortable with the traditional skiils as required by the smaw and gtaw process.The high weld energy and resulting higher weld fluidity of the flux cored weld provides flux cored consumables with their greatest asset for pipe welds, the potential for superior side wall penetration.Adding the gas cost to the electrode cost.50 per joint 12 per total consumable cost per flux cored joint versus 23 for the smaw electrodes per joint A cylinder of gas will last for 11 to 12 pipe joints.(12.5 - 15 cm).To attain across the board acceptance of the flux cored process, we decided that the best strategy would be to gather all the key weld personnel at a location in which both classroom and hands on weld training could be provided.Be knowledgeable of the electrode wire weld parameter ranges, and the parameter relationship with the weld equipment controls.However the flux cored process, described by one welder as a stick electrode on a 30 pound reel has a lot more in common with the prime attributes of the smaw process than any of the MIG processes.
