產品描述

符合標準:

GB/T 12470-2003 F48A4-EL8 AWS A5.23M-97 F7A4-EL8

 

認證機構:ABS, DNV, GL

 

說明:WD-SJ105是鋁堿型燒結焊劑,堿度約2.8(BIIW),為灰黑色球形顆粒,可交直流兩用,直流施焊時焊絲接正極,最大焊接電流可達1200A,粒度為10~50目。焊劑的熔敷金屬純凈,SiO2含量低,減少了硅的過渡,可得到較高的低溫沖擊韌性的焊縫金屬;焊后形成短渣,窄間隙脫渣容易,在焊接小直徑圓筒時不淌渣;焊縫成形美觀,電弧燃燒穩定,脫渣容易;抗吸潮性好,顆粒強度高,松裝密度小,焊接過程中焊劑消耗量少。配合相應的焊絲,采用多層焊、雙面單道焊、多絲焊和窄間隙埋弧焊等,可焊接較高強度船用鋼、壓力容器用鋼、管線鋼、海洋平臺及細晶粒結構鋼,用于重要的焊接產品。

 

用途:可用于船舶、壓力容器、貯罐、鋼結構、橋梁、螺旋焊管等結構的對接及角接焊縫。

Introduction
 
WD-SJ105 is an agglomerated aluminum-basic type flux with a basicity index of BIIW 2.8.The flux is black spherical granular.WD-68 can be welded with AC or DC at up to 1200A,connect the welding wire to the positive terminal when with DC. Grain size is from 10 to 50 mesh. As deposited metal is purity and SiO2 content is low, the transition of silicon is very low, so has very good toughness at the low temperature. Short slag is formed after welded, slag removal is easy in the narrow gap, and doesn’t drip slag when welding cylinders of small diameter. Bead appearance is beautiful, burn-out of the arc is stable, slag is easy to remove. The flux has low moisture pick-up and granular stability. As the bulk density is low, its consumption rate are few. With the matching wire,WD-68 is suitable for multi-layer welding, single pass welding in double side, multi-wire welding and narrow gap welding.WD-68 could be used for welding of high tensile steel for ship, steel for pressure vessel, steel for pipelines, ocean platform and fine grain structural steel. 
 
Applications
 
For flat fillet and butt welding of steel for ships, steel structures, pressure vessels, storage tanks, bridges and spiral pipes.

Typical mechanical properties of deposited metal
 
 
Notice:
1. Flux should be redried at 300~350°C for 2 hours.

 

2. All dust, oil and rust should be removed.
