A xem bong da truc tiep method that melts the base metal at the xem bong da truc tiep location to form the weld seam.
9. Root pass
The initial weld pass in single-sided groove xem bong da truc tiep that forms a backing (backing effect).
10. Cover pass
The final weld pass applied on the back side of a single-sided groove weld after the main weld is completed.
11. Full penetration weld
A weld joint fully penetrated from one side, generally referring to single-sided welds with double-sided formation.
12. Overlay xem bong da truc tiep
xem bong da truc tiep carried out to increase or restore the size of a weldment, or to apply a special performance overlay metal to the weldment surface.
13. Gas xem bong da truc tiep
xem bong da truc tiep process that uses a gas flame as a heat source. The most common is oxy-acetylene xem bong da truc tiep, though liquefied gas or propane gas can also be used.
14. Oxy-acetylene xem bong da truc tiep
xem bong da truc tiep method that employs an oxy-acetylene flame for joining.
15. Arc xem bong da truc tiep
A fusion xem bong da truc tiep method that utilizes an electric arc as the heat source.
16. Gravity xem bong da truc tiep
An efficient xem bong da truc tiep method where one end of the gravity xem bong da truc tiep rod is aligned with the joint of the workpiece, and the other end is held in a movable fixture. The rod is ignited, and with the arc burning, the xem bong da truc tiep rod is efficiently used due to gravitational force.
17. Carbon arc xem bong da truc tiep
An arc xem bong da truc tiep method using a carbon electrode.
18. Submerged arc xem bong da truc tiep
A xem bong da truc tiep method where the arc burns beneath a layer of flux.
19. Atomic hydrogen xem bong da truc tiep
A method where molecular hydrogen is thermally decomposed into atomic hydrogen between two tungsten electrodes. The recombination of atomic hydrogen into molecular hydrogen on the workpiece surface releases heat, serving as the primary heat source for xem bong da truc tiep.
20. Electroslag xem bong da truc tiep
A xem bong da truc tiep method that utilizes the resistance heat generated by electric current passing through a liquid slag. Depending on the electrode shape used, it can be classified as wire electrode electroslag xem bong da truc tiep, strip electrode electroslag xem bong da truc tiep, and nozzle electrode electroslag xem bong da truc tiep.
21. Electron beam xem bong da truc tiep
A xem bong da truc tiep method that employs accelerated and focused electron beams to generate heat for xem bong da truc tiep workpieces placed in a vacuum or non-vacuum environment.
22. Laser xem bong da truc tiep
A xem bong da truc tiep method that uses focused laser beams to generate heat on workpieces for xem bong da truc tiep.
23. Pressure xem bong da truc tiep
A xem bong da truc tiep method where pressure (with or without heating) is applied to the workpiece during xem bong da truc tiep. It includes solid-state xem bong da truc tiep, resistance xem bong da truc tiep, forge xem bong da truc tiep, diffusion xem bong da truc tiep, gas pressure xem bong da truc tiep, and cold pressure xem bong da truc tiep.
24. Diffusion xem bong da truc tiep
A solid-state xem bong da truc tiep method where workpieces are subjected to high temperature and pressure without visible deformation or relative movement. Filler metal can be pre-placed between mating surfaces.
25. Explosive xem bong da truc tiep
A pressure xem bong da truc tiep method that involves the rapid collision of workpieces due to the force of explosive detonation.
26. Ultrasonic xem bong da truc tiep
A pressure xem bong da truc tiep method that utilizes high-frequency ultrasonic vibrations for localized heating and surface cleaning of welded joints, followed by pressure application to achieve xem bong da truc tiep.
27. Resistance xem bong da truc tiep
A xem bong da truc tiep method that applies pressure to workpieces through electrodes, using the resistance heat generated by current flowing through the contact surface and adjacent regions of the joint.
28. Brazing
A xem bong da truc tiep method that uses a metal filler material with a lower melting point than the base material. The workpiece and filler material are heated above the filler's melting point but below the base material's melting temperature. Liquid filler wets the base material, fills the joint gap, and diffuses with the base material to achieve a connection.
29. xem bong da truc tiep rod
A consumable electrode for arc xem bong da truc tiep, coated with flux. It consists of a flux coating and a core wire.
30. xem bong da truc tiep wire core
The metal core within a xem bong da truc tiep electrode that is coated with flux.
31. Flux coating
A layer of coating applied to the surface of a xem bong da truc tiep wire.
32. xem bong da truc tiep wire
A metal wire used either as filler metal or as an electrode during xem bong da truc tiep.
33. Flux-cored xem bong da truc tiep wire
A type of xem bong da truc tiep wire formed by winding a thin metal strip into a circular or non-circular tube while simultaneously filling it with a certain composition of flux powder. The wire is then drawn to its final size.
34. xem bong da truc tiep flux
A substance used during xem bong da truc tiep that can melt into slag and gas, providing protection and metallurgical treatment to the molten metal. For submerged arc xem bong da truc tiep, submerged arc flux is used. For brazing, there are hard brazing fluxes and soft brazing fluxes.
