Question no. 9
Gmaw welding is drooping and flat characteristics??
Flat Characteristic ..
Drooping Characteristics: Drooping response as shown bellow generates very small variation in welding current compared to the variation of arc voltage. So this is also called as constant current power source.
capture-20180330-195729This type of power sources mainly used in manual welding processes like SMAW, GTAW as in this process frequent variation of arc voltage occurs due to variations in arc length, so it’s required to control the dramatic variations in welding current. This power source gives high voltage in no load condition, which favours easy arc ignition in SMAW process as it demands high OCV. These power sources are available with both AC, DC current variants.

REPORT THIS AD
Flat Characteristics: Flat response as shown bellow generates very small variation of arc voltage compared to the variation in welding current. This large variation in welding current used to achieve the “self regulating arc” with constant feed drive with small diameter electrodes (Small diameter gives rise to grater resistance heating). This “self regulating arc” phenomenon makes the welding process semi automatic.
capture-20180330-200343This type of power source mainly used in semi-automatic welding process like GMAW, FCAW, and SAW with small diameter electrodes. The slope selection of characteristics curve depends on welding process, electrode diameter and material etc, to meet the required welding conditions like type of deposition rate, type of metal transfer desired etc.
As “self regulating arc” cannot be achieved at small current densities like SAW process with large diameter of electrodes, continuous feed of electrode is achieved by using a variable feed rate controller which takes feedback from the changes in welding current.
Is Lamination comes in Welding or base material???
It is always in base metals
Sir I have pre-degree passed and I have an experience of 14 years in arc wedding and also have 50 years old. I am working in gulf.I am preparing for cswip exam. Shall I get a job as wedding inspector. I request your advice. Please reply.
In gulf lots of people in this age working as a welding Inspector
Thanks
Sir... Lamination will come in base metal or weld metal?
Lamination in weld means lack of fusion, in both weld and plate lamination can be seen
Good info ✨✅
Sir I have 10 years welding experience.i am interested in welding inspector course.sir possible or not possible give me some suggestions please.
Sure you can, you can do cswip weld certification course which is worldwide valid
q 14 rt after pwht or pwht after rt?
Always required PWHT after RT , I already explained in answer why need . However PWHT after RT its must required for before RT its totally client requirement.. For safe side sometimes we do both Before and After RT.
@@WeldingNDTInspection sir I am confused, RT is a none destructive testing, what is the significance of doing PWHT after RT, doing NDT after heat treatment makes sense, it's my humble doubt .please explain!
@@fredrickjose1976 good Question..see my answer.. Firstly RT after PWHT is not mentioned in ant code..its totaly depends on project specification, client requirements.
PWHT will relieve residual stress and can open up flaws which are otherwise closed by the residual stresses, and that is the reason why NDT for acceptance purposes is performed after PWHT.
Hello sir I am welding inspector your many answers of questions are wrong kindly make sure before upload video
Could you tell me the Question number ?
WQP - WELDER
Not weldING
Which question?
@@WeldingNDTInspection question no. 4
Apologies sir qus no 24 & 25 I don’t think ans is right
Yes both answers are correct, tell me what will be your answer.. Then I will explain you..
Purging is to avoid root oxidisation and shielding gas is to cover molten metal weld pool
