Welding the weld process equipment a!!!!! Is to ensure that the roots of penetration and weld joint on the back, and the back along the joint forming a preset foil device. The invention discloses a arc welding quality penetration ceramic liner material and its manufacturing methods. The ceramic liner material quality of the weight of the components percentage for: SiO2:40 to 60%, Al2O3:30 ~ 45%, Fe2O3:0 ~ 1.2%, MgO style and/or CaO: 3 ~ 18%, Na2O and/or K2O: 1.5 ~ 5%, the porosity is less than 5%. The production methods is in proportion to take these oxide powder or contains the oxide mineral raw materials, mixed granulation, powder abio-viscose, make the inorganic adhesive evenly covered in formed grains on the surface; Then the above covered with inorganic adhesive particle in the 75 ~ 150 N/pressure conditions was made blank; press pad Finally the liner stock in 1300 ~ 1380 ℃ temperature conditions, can be made into required sintering the contented quality gasket materials. The ceramic liner material qualitative low porosity, waterproof and tide ability, have to meet the requirements of the welding slag off sex and physical properties, no matter in a flat welding or soldering position, the weld made even smooth, without forming gas pit, ensure the quality of welding forming.
