One Piece Plate Is Normal
Due to typical stresses on sideplates of vibrating screen boxes, it is the norm to use one piece plate.
Welding would be a probable disaster in my experience.
BUT, some mfrs make 5' long modules....complete with flanged ends and bolt another 5'..........up to any length desired with separate drives on each module.

Re: Welding Sidewall Plates
Your question is a bit vague. Aren't there going to be any top & bottom flanges on your sides? Isn't a shaft boss often welded into the sideframe? I've even seen a (failed miserably) attempt to weld the deck plates to the sideplates to improve a delicate Turkish made screen. When I asked what electrodes had been used nobody was prepared to own up.
It is prudent to the point of essential to refer to Blodgett if you want to examine a proposed fabrication. Some of it can be downloaded from the Lincoln website.
Details from the one in front of me are "Design of Welded Structures" by Omer W. Blodgett ...the James F Lincoln Arc Welding Foundation...Library of Congress Catalogue Card Number 66-23123. Words like Lincoln & Congress might suggest the book is worth reading. It is, in its own right. Thank you America. ■

It can be done but you have to make some design "corrections" to accomodate the weld and "compensate" for it. The location of the weld has to be determined during design.

Welding Sidewall Plates
Dear Sandeep!
There are methods to determine roughly the stress in specific critic areas in the side wall. So you can determine which height or then plate width is really required.
By this size welding are generally possible , but in areas of less stress and deflection. For example in case of more decks than one a frame which makes the lower deck may be flanged on the original side wall or -reverse type- the drive may get flanged on the -by angle bars reinforced- side wall.
We can help you and give you some guidelines to solve this problem.
Your costs will run away by using stress release techniques, etc.

Welding sidewall plates
I just wanted to know if it is mandatory to use a single rolled plate for the side wall of the screen or if the width of the screen sidewall exceeds the standard plate size available in the market then is it possible to weld two plates together to the best quality and maybe get it radiographically tested and then stress relieve it before use.
Is it a safe practice. im asking this coz i need a 3.5 m wide plate which is not available in india. the maximum width rolled in india is 2.5 meters.
Im thinking of welding a 2500 mm plate and a 1000mm plate to make it 3500mm wide. ■
