cho mình hỏi cách vát mép đường hàn theo tiêu chuẩn IACS.Ví dụ cách vát mép mối hàn giáp mối tôn dày 10mm khi hàn hồ quang tay.Theo mình được biết thì việc vát mép phụ thuộc vào chiều dày tôn, phương pháp hàn, yêu cầu chất lường đường hàn...Nhưng mình chẳng có tài liệu nào về nó.Bác nào biết chỉ bảo cho mình với.Nếu có tài liệu nào về phần này cho mình xin để mình nghiên cứu cũng được.Địa chỉ của mình: [You must be registered and logged in to see this link.] .cảm ơn bạn nhiều

Mình cũng đang tìm nhưng chưa thấy !

Dear Vanthang, nguyentuyen,
I would like to discuss with you in English, We should improve our English right?
Caused I recognize that almost Engineers are English weak.
Come back our topic.
I just go by your topic which no one reply.
I would like to contribute something.
First, the edge preparation (chuẩn bị mép) depended on Shipyard WPS (Welding produce Specification), it means prior Shipyard construct any Project,QC dept. must prepare the WPS to submit to Class, and qualify for Welder to weld that project.
When got WPS and welder qualification, all works which are relevant to welding must strictly follow up WPS including:
Material (grade, thickness,...)
Consumable (electrode, wire,...)
Edge preparation (bevel, backing,...)
Welding position (2G,...)
So, you just follow up WPS
By the way, with 12mm in thickness (thk), butt weld, SMAW process, these plates have to bevel, if follow IACS there are many ways to choose, it base on you whether using backing trip or not. IACS shows clear very much.
I am interested in Welding field very much.
If you have any problem about this we can discuss to make clear any thing we can.
I hope you are satisfied.

Thanks and best regards,
QC Engineer.
