Shanghai Leierwo Industry & Trade Co., Ltd. provides professional welding mass production services, focusing on the connection and integration of high-quality, high-standard metal structural parts and complex components.
Welding is a crucial method, alongside casting and machining, for creating complex metal structures. It permanently connects separate metal parts through melting or plastic deformation to achieve specific structural functionality and strength requirements.
Our services extend beyond simple joining to include TUV-certified high-precision welding processes, assembly of complex structures, and structural reinforcement and repair for products subjected to extreme operating conditions (such as high temperature, high pressure, and severe corrosion). Leveraging our integrated industrial and commercial capabilities, we offer comprehensive, customized solutions, ensuring consistent product quality, reliable delivery schedules, and efficient global delivery.

Our Core Welding Capabilities

Core CompetenciesDescription and Advantages
Tuv Certified Welding ProcessOur TUV-certified welding process ensures that welding quality meets international standards. Key processes are performed by technicians with over 10 years of experience.
Complex Assembly And IntegrationFocus on the precise assembly of multiple cast or machined components (such as pump and valve components) into complex final products to achieve functional integration.
Full Process Quality ControlThere are 8 quality control nodes, covering from spectral testing of raw materials to non-destructive testing of finished products (such as PT/UT), ensuring that the qualified rate of products after welding reaches 99.5%.
Customized ProductionIt can flexibly meet the welding and assembly needs of single piece, small batch to large-scale batch production.

Wide Range of Applications and Core Products

Welding services are widely used in industrial fields that require high-strength connections and complex structural integration
Pumps, Valves and Connections：
Assemble complex pump bodies, valve bodies and flanges to meet the requirements of high temperature, high pressure and strong corrosion conditions.
General Castings：
Used for structural connection and reinforcement of large-sized or non-specific metal components such as construction machinery and marine parts.
Customized Structural Parts：
Produce a wide range of stainless steel castings, pipe fittings and structural parts to meet specific structural and dimensional requirements.

How The Production Process Works

We want to make working with us on a production project as smooth and streamlined as possible.

1

Speak with a manufacturing expert who will help you customize your production quote around a complete bill of materials.

2

Work with our team to optimize your project for production, including design for manufacturability and cost reduction options.

3

An initial sample run of the part is manufactured and sent to you to ensure the part meets your standards before full production begins.

4

Gain process transparency and quality control when full production begins.

5

Apply post-processing and final quality measures before parts are shipped.

6

Place subsequent batch production orders for your project at any time through our virtual warehouse.

ابدأ مشروعك مع لييروو

1. أرسل استفسارك
أرسل رسومات التصميم بمساعدة الحاسوب والملفات ثلاثية الأبعاد عبر البريد الإلكتروني، مع تحديد درجة المادة أو كمية الطلب أو تشطيب السطح أو أي تفاصيل أخرى ذات صلة.
2. حساب التكلفة
بمجرد استلامنا للتصميم الخاص بك، سيقوم فريقنا الهندسي بتقييم الرسومات بعناية وحساب السعر بناءً على تكاليف الإنتاج الفعلية في أقرب وقت ممكن.
3. بدء الإنتاج
بعد الموافقة على التسعير، سيقوم فريق الإنتاج لدينا بتجهيز المواد وتحديد موعد الإنتاج في أسرع وقت. تضمن لييروو دائمًا التسليم في الموعد المحدد.
4. ترتيب التسليم
بعد اكتمال الإنتاج، سنقوم بتوفير تفاصيل التغليف وترتيب الشحن عن طريق البحر أو الجو. نحن ندعم الشحن العالمي لكل طلبية.
