Cast Iron Welding Electrode Z208

GB/T EZC

AWS A5.15 EC1

Description: Z208 is a cast iron electrode with a low carbon steel core and a strong graphitized coating. It can be used for both AC and DC. The weld can become gray cast iron when it is cooled slowly, but its crack resistance is poor. Application: Used to repair defects in gray iron castings. Chemical composition of weld metal(%):

C	Si	Mn	S	P	Fe
2.0 ~ 4.0	2.5 ~ 6.5	≤0.75	≤0.10	≤0.15	Remain

Notice: 1. The electrode must be baked for 1 hour at 150℃ before welding operation; 2. The defects of less rigid parts in small thin-wall cast iron pieces can be welded without preheating, but general weldments need to be preheated up to around 400℃. If the weldments preserve heat and slowly cool down, they are on the cards that the soldering joints can bear cut processing. 3. This electrode is not suitable for important casting structures that are subject to stress and impact. Wenzhou Tianyu Electronic Co., Ltd. was established in 2000.
