Factory & Quality

Built in the factory, checked before it becomes a shipment.

This page is for buyers who want more than a polished product render: production context, practical checks, welding trials and the details that make an export order easier to sell and support.

Factory note 01 / Open assembly line

Machines are still open here, before final casing, testing and packing. This is where quality is visible.

01

Manufacturing platform

RILAND Group

DEYUN is now a RILAND Group brand. RILAND Group is a publicly listed welding equipment manufacturer in China, listed on the Shenzhen Stock Exchange under stock code 300154.

02

Assembly visibility

Open-machine workflow

Internal wiring, boards, cooling parts and machine layout are visible before final casing and packing.

03

Process check

Function, load, aging

Factory checks are practical: power-on behavior, wire feed, stable output and procedures that expose problems before shipment.

04

Welding proof

Arc, sound, result

Technicians judge the machine by more than a number on the screen: arc behavior, welding sound, wire feeding and the final weld sample all matter.

Production Evidence

Real production is part of the quality proof.

These images are treated as a contact sheet, not decoration. They show assembly flow, internal machine layout, component staging and finished machines waiting for delivery.

Checks before shipment

A welding machine should leave as a checked tool, not just a packed box.

The exact procedure depends on model and order, but the factory check logic stays practical: turn it on, load it, age it, weld with it, and inspect what the customer will receive.

QC-01

Function testing

Main machine functions are checked before packing.

QC-02

Load testing

The machine is tested under working load to confirm stable output.

QC-03

Aging test

The machine runs through aging procedures to expose problems before shipment.

QC-04

Welding trial

Arc behavior, wire feeding and welding response can be checked with real welding.

QC-05

Final inspection

Labels, panels, accessories, packaging and order details are checked before delivery.

Welding trial

Arc behavior, welding sound and the sample all have to agree.

In the workshop, experienced technicians do more than read numbers from a screen. During tuning and welding trials, they watch the arc, listen to the welding sound and check whether the weld result matches the expected behavior.

Configuration and export details

Quality also lives in the configuration.

A small difference in control, feeding, cooling or export setup can change how a machine works in a real workshop and how easily a distributor can support it.

Control

Knob-control models should feel direct and easy to adjust. LCD or digital-control models should give more precise setting control.

Cooling

Air-cooled and water-cooled machines should match the duty, heat and application intensity of the work.

Wire feeding

Integrated or separate wire feeders should be selected around workshop distance, structure size and service needs.

Market details

Panel language, labels, manuals, packing, documents and model configuration have to match the export market.

Shop-floor detail views

The small things still decide how the product leaves the workshop.

Around the machine, small details still matter: panel layout, connectors, weld samples, fasteners, staging and visual checks all shape how the product leaves the workshop.
